The overlaid text at the beginning says “Background noise is unrelated to this brain or the deceased.” Which is a really rather odd way of phrasing it.
Implied is that a different body is being dissected with those saws in the background, but, I’m not sure why that strange disclaimer is necessary in either case.
It’s not the only odd thing about the video… the contextless photo of a student eating at the beginning that Maggie points out is just bizarre. And while I guess there’s nothing wrong with the Zion National Park photo at the end, it’s still a bit out of place
It certainly rings true with my experience of university science culture, where people sometimes (often) don’t realize something they did seems odd to others.
I too wish that some more information was given, like an explanation of the pocket of blood (was that related to the cause of death? is that a stroke-causing blood clot? concussive injury?) but that obviously wasn’t the fairly specific point of the video. It was still very interesting and informative.
